SNMP Monitoring 11-3
• Unicast packets in
The number of subnetwork-unicast packets delivered to a higher-layer protocol.
• Unicast packets out
The total number of octets (bytes) transmitted out of the interface, including framing
characters.
• Non-Unicast packets in
The number of non-unicast (i.e., subnetwork-broadcast or subnetwork-multicast) packets
delivered to a higher-layer protocol.
• Non-Unicast packets out
The total number of octets (bytes) transmitted out of the interface, including framing
characters.
• Bytes in
Total number of octets (bytes) received on the interface, including framing characters.
• Bytes out
The total number of packets that have higher-layer protocols requested be transmitted to a
non-unicast (i.e., a subnetwork-broadcast or subnetwork-multicast) address, including those
that were discarded or not sent.
• IDU in discards
The count of valid frames that have been received which were discarded (i.e., filtered) by
the forwarding process.
• IDU out packets
The number of frames that have been transmitted by this port to its segment. Note that a
frame transmitted on the interface corresponding to this port is not counted by this object
unless it is for a protocol being processed by the local bridging function.
• In errors
The number of inbound packets that contained errors preventing them from being
deliverable to a higher-layer protocol.
• In discards
The number of inbound packets which were chosen to be discarded even though they were
deliverable. One possible reason for discarding such a packet could be to free up buffer
space.
• In Alignment Errors
A count of frames received on a particular interface that are not an integral number of
octets in length and do not pass the FCS check.
• In FCS Errors
A count of frames received on a particular interface that are an integral number of octets in
length, but do not pass the FCS check.
